Redfin Scraper & Investment Analysis

Scrape Redfin property data across locations

Enter ZIP codes or Redfin city/ZIP URLs and receive structured listing records, sample market summaries, and optional sold comparisons and investment calculations. This Redfin scraper helps compare asking prices, screen properties, and export real estate market data through Apify's property data API.

Public V1 returns up to 100 properties per location, across up to 10 locations. It reports coverage explicitly. Investment metrics depend on available property data and your assumptions; every property does not receive complete underwriting.

Key features

• Redfin listings scraper for active, sold, rental, pending/contingent and coming-soon inventory.
• Structured IDs, address, price, beds, baths, square feet, property type, status and listing URL.
• Price per sqft and price-drop amounts/percentages when source values exist.
• Redfin comps selected from sampled sold homes using disclosed similarity rules.
• Sample market pricing, property-type distribution and collection timestamps.
• Mortgage, ownership, NOI, cap rate, cash-on-cash and DSCR calculations when inputs permit.
• Deterministic Deal Score with components and coverage.
• JSON/CSV export and preservation of valid locations when another fails.

Supported listing types

Input value	Output
forSale	Active listings
sold	Redfin sold homes within soldWithin
forRent	Rental listings; source ranges use the minimum value
pending	Pending, contingent and under-contract source statuses
comingSoon	Coming-soon listings in the exposed search sample

Multi-location searches

Use ZIP codes or city/ZIP search URLs. A Redfin property URL is not a supported search input. City-name text lookup is experimental; ZIP codes and URLs are preferred.

{
  "locations": ["78704", "https://www.redfin.com/city/30818/TX/Austin"],
  "listingType": "forSale",
  "maxResultsPerLocation": 100
}

Results retain their first input location. Duplicate listings across overlapping locations are emitted only once per run; each summary describes the newly emitted records for that location.

Sold comps

Enable includeComps to compare properties with up to 100 sampled recent sold records. Candidates must share a normalized property type. Where values exist, they must be within three miles, one bedroom and 25% of target square feet. Up to ten nearest candidates are selected; ties use stable IDs.

Output includes comparable IDs, counts, median price and the target's percentage difference from that median. The time window uses soldWithin (default three months). These are screening comparisons, not an appraisal. If the sold search fails, base properties remain available and a warning is logged.

Market analysis

Each location receives one MARKET_SUMMARY with count, median/average price, price per sqft, days on market and property-type distribution. Every statistic describes the collected sample, not the entire market.

CAPPED means the user limit or source response limit restricted collection. PARTIAL means full-market completeness has not been established. Public V1 does not claim COMPLETE.

Investment analysis

Set investmentAnalysis.enabled to true for transparent real estate investment analysis. Mortgage estimates require a valid purchase price. Ownership cost requires known tax and HOA. Rent-based metrics additionally require monthlyRentOverride.

Automatic Redfin rent estimates are not part of V1. When required data is missing, the affected metric stays null. Rental asking prices are not silently treated as sale prices or as a source rent estimate for another property.

Input

The Store form has four sections: Search, Filters, Analysis and Advanced.

Input	Default / meaning
locations	ZIP 78704; up to 10 locations
listingType	forSale
maxResultsPerLocation	20; maximum 100
Price, beds, baths, sqft, property type	Optional filters applied to the exposed search sample
includeComps	false
investmentAnalysis	{"enabled": false}
proxyConfiguration	Direct networking unless supplied

Property detail enrichment is disabled in V1. Detail, photo and history flags set to true are rejected before network work.

Output

Important property fields appear first in the Dataset: address, price, asking rent, beds, baths, sqft, property type, status, price per sqft and URL. For rental searches, askingRent is the source listing's monthly asking price; price retains the same value for backward compatibility. rentEstimate remains null unless an independent estimate is available. Stable IDs and timestamps support downstream comparisons. Optional analysis is nested; unavailable property fields are null.

PROPERTY rows contain listings. MARKET_SUMMARY rows contain sample statistics. ERROR rows report failed locations. Filter by record type for property-only exports. In a mixed table, columns that do not apply to a record type may be blank.

Example

Fast default:

{
  "locations": ["78704"],
  "listingType": "forSale",
  "maxResultsPerLocation": 20
}

Assumption-based analysis:

{
  "locations": ["78704"],
  "listingType": "forSale",
  "maxResultsPerLocation": 20,
  "includeComps": true,
  "investmentAnalysis": {
    "enabled": true,
    "monthlyRentOverride": 3500,
    "propertyTaxPercentAnnual": 2,
    "downPaymentPercent": 20,
    "interestRate": 7,
    "loanTermYears": 30
  }
}

The tax-rate assumption is used only when source tax is absent. This example can calculate returns for a condo with known HOA, while a house with unknown HOA retains null returns.

Financial assumptions

Defaults when analysis is enabled: 20% down, 7% interest, 30-year loan, 3% closing costs, 0.5% annual insurance, 1% annual maintenance and 5% vacancy. These are editable assumptions, not current market quotes.

NOI excludes debt service. Cap rate is NOI divided by price. Cash-on-cash deducts debt service and divides by down payment plus closing costs. DSCR is NOI divided by debt service. Percentages are percentage points: 6.8 means 6.8%. Unknown tax/HOA never silently becomes zero.

Analysis of purchase financing is intended for sale/sold/pending/coming-soon records; rental searches return listings without purchase-financing calculations.

Deal Score methodology

No AI is used. Six components are clamped to 0–100: comp discount, price drop, days on market, cap rate, cash-on-cash and DSCR. Their available-component mean is emitted only when at least two exist. dealScoreCoverage is the available fraction of six, not a confidence probability.

Component formulas: clamp(50 − 2 × comp premium percent), clamp(5 × price-drop percent), clamp(100 × days/90), clamp(100 × cap rate/10), clamp(100 × cash-on-cash/12), and clamp(100 × (DSCR − 0.8)/0.8). Longer time on market is a negotiation signal in this heuristic. The score is a screening aid, not investment advice.

API & automation

Use this Redfin data scraper through Apify Console, the Apify REST API or JavaScript/Python clients. The property data API exports JSON and CSV for spreadsheets, databases, Make, Zapier and n8n workflows. It is an independent Redfin property scraper, not an official Redfin API.

Scheduling / monitoring

Use Apify schedules to collect snapshots. Compare stable property/listing IDs externally to track changes in Redfin real estate data. V1 does not include a separate change-detection or notification engine.

Pricing

Price: $2 per 1,000 PROPERTY records, plus Apify platform usage shown separately. Optional comps and investment calculations have no additional event fee. There is no startup, summary, error or enrichment fee.

The live Store pricing panel is authoritative. Failed searches can still incur platform compute/proxy usage even when they deliver no billable property records. A named property event excludes summaries and errors; overlapping-location duplicates are not emitted or charged again.

Limitations

• Maximum 100 results per location. Large-market completeness is not claimed; filters operate on the available sample.
• Source availability and MLS fields vary. Missing history, tax, rent estimates or contact data is expected.
• Detail enrichment is disabled. No bulk-enrichment claim is made.
• Rent returns require user rent; unknown tax/HOA suppresses dependent metrics.
• Direct networking passed small cloud runs but may be denied under sustained activity. US residential Apify Proxy is a tested, more expensive option. Standard datacenter proxy failed validation.
• An empty market emits a summary and the run fails if no location produces properties.
• Redfin website routes can change. Use the data within your applicable access and data-use rights.

FAQ

Can this Redfin rental scraper calculate returns automatically? No. Rental records are collected, but returns on a purchase require a valid sale price, user rent and known material expenses.

Does it collect every matching home? No. V1 returns bounded samples with coverage labels.

Can I export Redfin sold homes and comps to CSV? Yes. Use Dataset export and choose the fields needed; nested analysis produces extra CSV columns.

Why is a metric null? A necessary price, expense, rent or denominator is missing. Supply supported assumptions where appropriate.

Why keep “Investment Analysis” in the title? The Actor provides sold comparisons, mortgage estimates, conditional ownership/return calculations and disclosed scoring, while showing exactly which inputs are available.
